+# Chat Channels
+
+## Overview
+
+OpenClaw integrates with numerous messaging platforms through its Gateway infrastructure. The documentation lists 20+ supported channels, with text support available universally while media and reaction capabilities vary by platform.
+
+## Supported Platforms
+
+The primary channels include established services like:
+
+- **WhatsApp** - Using Baileys with QR pairing
+- **Telegram** - Via grammY bot API
+- **Discord** - With server and DM support
+- **Slack** - Through Bolt SDK
+- **Signal** - For privacy-conscious users
+- **iMessage** - BlueBubbles recommended for integration
+
+## Key Features
+
+Channels can run simultaneously; configure multiple and OpenClaw will route per chat. This enables users to maintain presence across multiple messaging services with a single bot instance.
+
+### Platform Differences
+
+- **WhatsApp** setup requires QR pairing and maintains more local state
+- **Telegram** offers the quickest configuration path using only a bot token
+- **BlueBubbles** supports advanced iMessage features including message editing, unsending, and reaction handling (though edit functionality is currently broken on macOS 26 Tahoe)
+
+## Plugin-Based Extensions
+
+Several channels require separate plugin installation rather than core integration:
+
+- Feishu
+- Mattermost
+- Microsoft Teams
+- Matrix
+- LINE
+- Zalo
+
+## Security
+
+DM pairing and allowlists provide security controls. See the individual channel documentation for specific configuration options.
